A change before the Spa 6 Hours, round three of the 2023 WEC, was the only opportunity for revision in the first half of the season under a new BoP system introduced for 2023.
The BoP for the first four races up to and including Le Mans was set ahead of the season-opener at Sebring in March, with a shift in the balance between the Le Mans Hypercars and LMDh machinery being the only permissible change after two races.
Rule makers the FIA and the Automobile Club de l’Ouest confirmed that there would be no tweaks to the so-called platform BoP for Spa on Thursday morning ahead of the start of free practice.
The next opportunity for change will be after the double-points Le Mans round on 10/11 June when the platform BoP and the manufacturer BoP can be revised.
This will allow for wholesale changes for all cars from the seven makes represented in Hypercar this season.
The BoP will then be set for the remainder of the season, with a possible platform revision after a further two races in time for the season finale at Bahrain in November.
The latest system is based on simulation rather than lap-time data and has been devised to remove the possibility of sandbagging in order to gain a favourable BoP.
The FIA’s Endurance Committee has also approved a request by Michelin to allow all three specifications of slick tyre available this year to be used at Spa.
